To all whom'it may concern: Y

Bo it known that 1, .FREDERICK Bini.. GLENN, a citizen of the United States'fresiding at Lynehburg, in the eounty oi Campbell and State oi'virginia, have invented a. new and useful Adding-Machine, of which the'lollowing is a speeifi'cution.

. JSimilar"referenze Ynumerals designate corresponding parte in all thorigures of the drawings.

In the einliodiment illustrated, a frame casing ris employed tliatmay be of `any suitable shape, and is preferably `supported by end standards 6. Upon the top 7 .of this easing is mounted a register disposed at en inclinutien'and supported on legs 8 fastened to said top; The register consista of a casing 9;, within which are dis'poried a lplurality o rotatable number Wheels l'ond 11, two Vboing shown, though any number can be elnployed, as will 'be evident to those skilled inthe ort. One'o the wheol l0, is provided with a consecutivo series oi `nunilmrs iront zerojto'lno, the other l1, haw inga euries from zero to twenty-nine. The Wheel 10 is provided with a peripheral series oi ratchet teeth 12, with which 'a springpreseed dog V13 eoperatoo, said dog perrnit'ting'tln-frotation of the wheel in one direction, but preventing'its ri-.tmgrudo movement. The Wheel 11* is also provided'with a eoreh oi rutr'luet tooth 14, und e"Iiriug-proserl dbg 'l onion-ratio therewith. -The -teblo shoit 2l that extends downwiii'i'liy :it affini-linotiou lnenoath the rogiuter und through the top 7 oi the machine easing.- A disk or wheel22 is fixed to the 1 8, in tho top oilho voering, tho opening ll-l boing;'in-the;V

lower -end of the rotatable shaft, and has arperipliorel series of notches 23, forming teeth 24 between them.

A pinion 25 i journaled upon the lower portion of the shaft 21 and iarsupported thereon by the d isk or toothed wheel 22. A spring pressed dog 26, mounted on the disk or toothed wheel 22, is arranged to engage the pinion 25, and thus it will be evident that il the pinion 25 is rotated iu one direction, the dog, interlocking with the teeth of said pinion, will cause the rotation oi the disk or toothed wheel 22, and consequently oi the their, 21, thereby effecting the operation oi thu register. The means for moving the pinion 25 is preferably coustru: l as foliows:-A rock shalt 27 is journaled within tine machine easing, and is provided with u quiuh'nnt-gour that meshes with the pinion 25, ambie disposed above the path of movement ol the dug 2G. The rook shaft hasV au offset portieri 29 that extends around tho rotatable shaft. iengtlie are terrieri by tne rock shalt, and ure normally diepoeed in substantially horizonud relation. A spring Shengaging one ol the arno, serves to hold the orion of arms and the rock sluil't in u. predetermined punition. e't permitting the downward niowinout ul the former. A plurality oi reciproeutory number kein-Gill nre diopoesed along the iront uuu-gin oi' the mawiiine fusing uml Vhave upright. stems 33 pinning downwardly thorethougli, with their lower ondel rosiinl; in fio-.its 3l, orrxiioil in theuppot side oi the Tree omis el' ilse :irma Si). The keys are provided with muneml designations one to nine inehisive, im shown in lrig. l. The "one" Rey preferably eopemteo with the longest erm, und the nine key with tho shortest. 'lhe vin-ione key stems are preferably provided with oll'sot l'eet 35, lluit are located at one side ol the onus, n shown in Fig. 1l.

To prevent overthrow of the register, n roi-k sli-.tit :h is journaled in the lnnohiuo easing, in iront oi :ind liolow the rock shialt 27, land hush slop dog il? nor-molly disposed beneath the disk 2;! und niovuble upwardly into theuotclaes thereof when tnid notches oline with the dog.' This roel: shrill, furthermore hun :1. plurality of urine 38, the ends of which uro dia-[nood ut ilillorexit heights, iuidareruspectively loeuted in the paths oi luovetneut oi the ieet ol the key stems. The highest A plurality oi :irme 30 el' different ill;

oi the urmn is disposed lione-nth the lool. ni' the liey theregister wheels arranged so that the neurali-nig# ,nations are'jexposed, the keys und the gonring boing' prdfieriy proportioned, upon thenlepreosion of :my

keyftiie wheel 10 will be revolved e sutiieient distance to expose the number oi the wheel lll eorrmponding to the key depressed. Therefore, upon the consecutive operation oi the different keys, it will be evident that addition will be performed, and the result disclosed by the register. When a key is depressed, the quadrant-gear 28 operates upon the pinion 25 so as to cause the rotation of the dog 26, the disk 22, the shaft 21, and consequently the nnmbcr wheel or wheels. When the shaft returns, under the impulse of the spring 3l, the pinion 25 will rotate freely and the dog 26 will ride over the teeth thereof, while retrograde movement of the register wheel l0 will be prevented by the dogl. Moreover, as the key nears the limit of its dowri-stroke, its foot will engage one of the arms 3SL thereby rocking 'the shaft 36 and raising the dog 37 into a notch of the disk 22, preventing overthrow of the register. Upon the return of the key, the dog moves downwardly, a spring Sil beingpreferably employed for effecting the return movements of the rock shaft 36, the arm 38and the dog.

From the foregoing, it is thought that the construction, operation, and many advantages oi' the herein de scribed invention will be apparent to those skilled in the art. without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacriiic ing any of the advantages of the invention.
